Singer Aubrey O'Day and reality TV star Pauly D have parted ways after less than six months of dating.

The ex-Danity Kane star grew close to Jersey Shore's DJ Pauly D last year (15), as they filmed reality show Famously Single, in which a group of unlucky-in-love celebrities attempts to live together in a Los Angeles apartment, while tackling a series of relationship woes with the help of therapists and dating experts.

They struck up a romance in November (15), but Pauly's representative has now confirmed to Entertainment Tonight that Aubrey and her man have since called it quits.

The news emerges just two weeks after the 32-year-old blonde gushed about Pauly on Instagram.com after posting a photo of the couple kissing.

"He gets my rocks off," she captioned the sweet image.

Aubrey has yet to comment on the break-up.
